PENCIL.

Application inea March 22,1928. serial No. 263,83?.

This invention relates to pencils and has fora. particular objectthereof the provision of a pencil which may be readily sharpened Withoutthe assistance of a knife or other cutting implement.

A further and more specific object ot the invention is to provide apencil, the lead of which is provided With a. casing formed oi parafiineor some other suitable 'Wax-like substance, Which will not solten fromthe heat ot the hand and which, at the same time, may be readily removedfrom the lead bythe appli cation of heat thereto or scraped from thelead by the use of a thumb nail or a blunt instrument. 1

These and other objects I attain by the construction shown in theaccompanying draiving, wherein for the purpose of illust.v is shown apreferred embodiment ot' my invent-ion and Whe-rein Y j Figure l is aside elevation of a pencil constructed in accordance with myinvention;

Figure 2 is an enlarged longitudinal sec tional view therethrough;

Figure 3 is a. transverse sectional view therethrough.

Referring now more particularly to the drawings, the numeral l0generally designates a. lead olf the type 4ordinarily employed inpencils which, in accordance with my invention, is surrounded by a castcasing ll consisting of either a pure paraliine or parafiine mixed WithWax and other substances to produce a composition which Will not melt atbody temperatures and which, at the same time, may be readily melted bythe heat or a match applied thereto. Aboutthis casing, I provide a papercover l2, the edges ot which are joined to one another. This entire tubeis joined to the casing ll. in the process oi casting the same andserves to reinforce the casing and render the same rigid und-erslightlyhigher temperatures to Which it might be subjected While 1n storage.This pencil may have applied to one end thereot an eraser 1,3, which isconnected to the aencil in the ordinary manner.

A pencil of this character may be sharpcned by the use of a bluntinstrument or ma y be sharpened by simply light-ing a match and applyingthe flame to the end ot the pencil to melt away the casing and burn awaythe cover.

Since the construction hereinbeiore set torth is capable ot a certainrange ot change and modilication Without materia ly departing from thespirit ofthe invention, l do not limit myseli2 to such specificstructure except as hereinafter claimed.

l claim l. A pencil comprising` a lead and a surrounding casing of asubstance maintaining its rigidity under body temperatures but meltingreadily upon the application ot' thune thereto.

2. A pencil comprising a lead and a surrounding casing ot a substancemaintaining its rigidity under body temperatures but melting readilyupon the application oi flame thereto, and a cover tor said casing whichis readily sectionally removable and reinforces said casing to stitlenthe same and render the same rigid under temperatm'es Which wouldotherwise permit the casing to flex and deform. v

3. A pencil comprising a lead and a snrrounding` casing of a substancemaintaining its` rigidityl under body temperatures but melting readilyupon the application ot llame thereto, and a reinforcing` cover for saidcasing of readily combustible material.

t. A pencil comprising a lead ane a surrounding casing of a substance.maintaining its rigidity under body temperatures but melting readilyupon the application of flame thereto, and a paper cover tor saidcasing.

ln testimony whereof I hereunto aliix my signature.
